Description
- This invention relates to an electrical connector and more specifically to an electrical connector holder to hold a pair of electrical connectors in parallel with each otner.
- In a certain electro-mechanical device, it is desirable to supply two parallel independent electrical connectors each having a desired number of receptacle contacts disposed in a single row along the length of a housing at a constant pitch. Such independent connectors are electrically connected to a matable electrical connector naving two rows of pin contacts disposed along the length of the housing at the corresponding pitch.
- Conventionally, a box-type holder is formed having an opening only at the one side plane along the rear surface from which electrical wires extend. Connectors having receptacle-type contacts are mated in parallel from the open side plane of the holder. Under this mated condition, the connectors are electrically connected by mating with a matable connector having male contacts.
- It may be possible to make a single connector by integrating two connectors having female contacts in order to meet the above needs, thereby eliminating the need for the holder. However, in such a connector for making insulation-displacement connections between contacts and electrical wires, such insulation displacement connection is made either separately for each row of contacts or simultaneously for the two rows of contacts. The former process is not suited for high speed production because insulation displacement connection is repeated in two steps for the first and second rows of contacts and the connector must be turned over. The latter process is not applicable to currently available automatic production machines because of its technical difficulty.
- The above holder is bulky due to having both sidewalls along its length. Therefore, such a holder is not suitable to meet an overall compact connector design.
- In addition, a connector having a relatively large number of contacts requires a relatively larger holder to mate with such connector. The larger the connector and the holder, the higher is the insertion and extraction forces therebetween, thereby requiring that they be constructed with increased holding strength. This further increases insertion and extraction resistance of the connector into and out of the holder, thus resulting in poor operability.
- Another problem associated with a larger holder is increased warping of the sidewalls along its length, which results in poor operability of the connector with respect to the holder.
- It is an object of this invention to provide an electrical connector holder which alleviates the above problems and in which connector-holding chambers are formed by a center wall in place of the opposing sidewalls of the prior holder, and connector engaging means is disposed at desired locations for holding an electrical connector in each chamber.
- Hence, the invention consists in an electrical connector holder for holding electrical connectors having electrical contacts secured in dielectric housings, comprising a front wall, a centre wall extending along the front wall, and end walls at the ends of the centre wall, whereby the connectors can be positioned along the front wall on opposite surfaces of the centre wall between the end walls, first latch means on the end walls engageable with ends of the connectors, and second latch means engageable with the connectors for causing the front surfaces of the connectors to engage the front wall, said front wall having apertures at the same pitch as the contacts in the connectors.
- In a preferred embodiment, the first latch means engage ear members on the connector end walls at substantially a central position of the width of the connectors to be latched in the holding chambers. The second engaging means are located on the centre wall for engaging rear surfaces of the connectors.
- In greater detail, the first latch means may be projections extending inwardly from the free ends (remote from the bases) of the end walls and projecting over the center wall. The second latch means may comprise of at least one projection on the center wall at the remote edge from the front wall in an intermediate region along the length of the center wall. The projection has a sloped outer surface and an inner surface essentially at a right angle to the plane of the center wall.
- In a connector holder of the above construction, the connectors are latchably maintained in the connector-holding chambers separated by the center wall. The latchably maintained condition is further enhanced by the first latch means on the end walls and the second latch means on the center wall. The two connectors thus retained by the holder are mated with a mating connector. As a result, contacts of the latter connector are electrically connected to contacts of the former connectors by way of the apertures disposed in the front wall of the holder at a constant pitch.
- A preferred embodiment of the present invention will now be described by way of example with reference to the accompanying drawings, in which:
- FIG. 1 is an exploded perspective view of an electrical connector holder and an electrical connector according to the present invention.
- FIG. 2 is a rear elevational view of the holder in FIG. 1.
- FIG. 3 is a rear elevational view of the holder with two connectors latchably positioned in upper and lower chambers of the holder.
- Shown in FIGS. 1 and 2 are a
holder 10 and one of the twoconnectors 20. Theholder 10 is preferably made of a flexible plastic material and comprises an elongatedfront wall 11 facing a mating connector (not shown), an elongatedcenter isolation wall 12 integral with the center of thefront wall 11 and extending along the length thereof, andend walls front wall 11 and thecenter isolation wall 12. The height of the end walls is chosen to be slightly shorter than the height offront portions center isolation wall 12. Formed at the upper ends of theend walls end walls 14a, 14 are first latch means 15 extending inwardly therefrom. There are formed second latch means 16 in the form of triangles with sloped outer surfaces at the rear edge portion of thecenter isolation wall 12 opposite to thefront wall 11 at a constant pitch along the length thereof.Apertures 17 are formed near upper and lower edge portions of thefront wall 11 in correspondence with the arrangement of female contacts (not shown) secured in theconnector 20 at a constant pitch. Male contacts of mating connectors extend through theapertures 17 for making electrical connection with the female contacts. - Each
connector 20 includes ahousing 21 which is made of an insulative material such as plastic and hascavities 22 at the pitch of the female contacts. In FIG. 1, thecavities 22 are open at a rear surface and a bottom surface of thehousing 21. The female-type contacts in whichelectrical wires 27 are insulation displacement connected are mounted into thecavities 22 from the open bottom surface and engaged by flexible engagingmembers 23 to prevent backward movement. There are formed on the outer surface of theend walls housing 21 at a substantially center position thereof,ear members holder 10. The width of thehousing 21 transverse to the longitudinal direction thereof is chosen to be substantially equal to the distance between the inner surface of thefront wall 11 of theholder 10 and the inner surface of the second latch means 16. The height of thehousing 21 is chosen to be substantially equal to the height of thefront wall projections 26 on the upper surface of thehousing 21 near both ends thereof to prevent inverted mating theconnectors 20 with theholder 10. In this way, a pair ofconnectors 20 are prevented from unintentionally moving or slipping out in any direction. As understood from FIGS. 2 and 3, in the latched condition, there is no portion of theconnectors 20 at upper and lower edges of thefront wall 11, the upper ends of theend walls end walls holder 10. In order to remove theconnectors 20 from theholder 10, for example, a group of theelectrical wires 27 are engaged to gently pull the rear side edge of theconnector 20 toward thefront wall 11 with the front side edge of theconnector 20 acting as a support. - As described hereinbefore, when the
connectors 20 are mated with or removed from theholder 10, theend walls ear portions - Since the
end walls holder 10 can be deflected outwardly as described above, theconnectors 20 may be mated with theholder 10 from the rear direction. However, this operation is relatively difficult as compared with mating in a vertical direction from the upper or lower direction. It is therefore normal to mate or remove in a vertical direction. Theprojections 26 are provided to prevent theconnectors 20 from being mated with theholder 10 in an up-side-down direction. Additionally, the second latch means 16 is most preferably formed on thecenter isolation wall 12 as in the illustrated embodiment. This is sufficient to prevent theconnectors 20 from unintentionally slipping out backwardly. However, if theholder 10 and theconnectors 20 are relatively short, such second latch means may be formed at appropriate locations of theend walls - As the center isolation wall is formed along the center of the front wall of the holder with the side walls of the holder facing and latchably engaging connectors positioned therein, the holder is a low profile design as compared with a conventional box-type holder and economical with minimum molding material for the holder. Despite this construction, when the holder is mated with two connectors, latch means are provided to firmly secure the mated connectors therein and prevent unintentional movement or slipping out of the connectors in any direction.
- Also, such a holder construction overcomes any disadvantages associated with the conventional elongated connector design having a large number of contacts, i.e., increased insertion and removal forces of the connectors into and out of the holder. Rather, such particular construction of the holder ennances flexibility to ease insertion and removal operations of the connectors. The center isolation wall may be relatively thin; because with the connectors mated with the holder, the center wall is strengthened.
